AERATOR FOR LIQUID-DISENSING DEVICES. q

Elimination filed Api-ii s,

This invention relates in general to a valve structure particularly adapted for use with liquid dispensing apparatus and more p particularly to a combined liquid controlling and air supply valve mechanism.

In the use of liquid dispensing apparatus there are many situations wherein it is necessary `or desirable to bring about an aeration of the liquid in the receptacle contemporaneously with the withdrawal of liquid through the dispensing faucet. In many cases it is desired also to pass the supply of air which enters the body of liquid through a chamber containing some substance or agency for acting on the stream of airflowing therethrough in order to affect insome way the liquid within the container. Devices have heretofore been constructed for carrying out an aeration ofthe liquid in a container in the general manner referred to. These devices included. the admission of air through a control port in an otherwise airtight cover for the container. This form of construction is objectionable in that a rise in temperature of the atmsophere surrounding the container tends to expand the contents of the container to a degree such that liquid is forced upwardly into the aerating tube and through the port inthe cover mem-. ber. In the event that a chamber for air` treating substances is introduced in the aerating tube, the liquid passes into the chamber and makes direct contact with the substance therein which'destroys or tends to destroy the effectiveness of the device.

A general object of the present invention is to provide a liquid aerating `device for liquid dispensing apparatus which will be` free from the `objections referred toI and` which will insure the automatic aeration of the liquid simultaneously with the operation of the dispensing valve and at the saine time prevent interference with the aerating structure by the liquid contents of. the container.

The invention includes an air valve structure through which air is drawn into the container to replace the liquid withdrawn therefrom by the operation of `the liquid dispensing device, the` air valve being ar-` ranged to` be invariably and simultaneously operated when the liquid dispensing valve isoperated.` i i y A feature of the invention resides in the mounting of the air valve structure on the 1927. sei-mi Nia/181,482.

With this arrangement when `the dispens-` ing valve is actuated, the air valve is siinultaneousl.` actuated and as liquid is withdrawn tirough the faucet air is simultaneously permitted to enter the aerating tube and to emerge at the free end of the tube near lthe bottom of the container and the mass of liquid held therein. It will be seen that with this construction air cannot rise within the open end of the tube because of the'volume of air pocketed therein between the open end of the tube and the control valve therefor, so that liquid cannot rise to the bend in the tube in the upper portion of the container;

A .feature of the invention resides in the provision in theI aeratingtube near the uppermost portion or return bend therein of a chamber whichcan be readily opened and in which any desired substance for treating1 or filtering the air passing through" the tube may be placed. n y

n By providing an airtight cover for` the container all thejair which enters the` container to replace liquid withdrawn therefrom is constrained to controlling valve referred to so that the desired control of the aerating process is obtained. i

liquid dis ensing deviceequipped Withan aerating evice embodying the invention.

Referring to the dra-Wings fora more detailed description of the invention, aliquid container structure is shown in lFigure 7 of thedravvings and comprises an open top vesvsel 10 having a close fitting lcover member 11 which can befclamped into airtight relation vviththe upperend of the jar through the n engagementfof a cam member 1.2 against the upper'surfa'ce of the cover. The cam member- 12 is .formed integrally ivith a handle member -13 pivotally ymounted at 14 on a bail-like member :IjmOunte'd `on 4thev conm tainer structure. 'i

' aerating structureand a control valve there-V Tlie container 10 isfpr'ovided near its lower end with a faucet 16 firovided Witha valve actuating member 17 in the outer extremity thereof. 1

The 'e invention' herein has to do With an for which are closely'` associated with the dispensing faucet rstri'ictufre 16 referred to. The'aerating structure` includes a vertical tube 18 Which rises from lthe inner end 19 of the faucet structure 16 and is bent back on itselfl at20 near theupper end of the container. The return branch 21 of the tubular member terminates at 22 at a point near the j lower end of the container andalso near the 'e lowest point of the mass of liquid 23 which is held in the .receptacle or container 10;

Y4K5 f diical portion 19 of the faucet 16 ywhich The aerating tube 18 has a horizontal eX- tension 24 Whicli-extends through the cylinpenetratesthe side Wall of the container 10.

The horizontal branch tube 2 4 communicates Withra vertical tube' section 25' Which opens into avalve chamber `26 which is controlled bya valve member 27 normally held against -anannular Lseat 28 fbythe pressure of a spring 29 thereagainst. The valve member 27I isI provided with a stem BOIWhich extends forwardly'through a tubular` housing 31 and.,A ,i islanchored in anactuating member 32`which i isfprovidedvivitha'dovvnvvardly extending arm`33 attachedat 34`toft'he outenend of the actuating member 'of the dispensing faucetfrlt.,l The'actuatingrmember 17 which is iii-the form offa pushbuttoii or'push memberbears againstthe stein 35 of a valve member 36 which normally occupies lseated engagement 4with a' shoulder or seat 37' in the faucet "s'tru'cture." The valve member 36 controls the flow of liquid through a discharge port 38 While the valve 27 controls the flow of air through an inlet port 89 and thereby through the aerating tube 18 into the interior of the mass of liquid in the container.

With this structural arrangement operation of the dispensing faucet 16 to withdraw liquid from the container l() is invariably accompanied by the'siniultancous'opening or unseating of the air valve 27 from the seat 28 so that as liquid is delivered from the container through the port 38 air enters the container through the port 39 to replace the liquid withdrawn from the container. It Will be seen therefore that the admis-:sion of air to the container is completely controlled and is automatically brought about through the operation of the dispensing laurci.

In order to filter the air thus drawn through the aerating tube into the liquid in the container 10 or to otherwise treat the aii as it is passed into lthe body of liquid, a chamber 40 is inserted into the aeraiing lube structure at an elevated point near the uppermost part 2() of the tube. The chamber 40 includes a cup member 41 earned at the upper extremity of the tube branch 2l. 'lhe cup member 41 is arranged to have threaded engagement with a cover member 42 carried by the return portion 43 of the aerating tube 18 so that the chamber can be readily opened for inspection or to replace the coutruis thereof. Any desired substance or material may be placed in the chamber 40 depending` upon the treatment that it is desired to produce in connection With the air entering the liquidin the container.

In a modified form of the invention shown in Figure 4 of the drawings, the control valvestructure for the aci-ating device is mounted almost Wholly Within the faucet structure. By reference to Figure llit will be seen that an air control valve 44 is mounted foi' normal engagement with a seat 45 mounted at the outer end of a horizontal biaiicli tube 46 which occupies a position extending from the inner end of the faucet barrel 19; The valve 44 is mounted at the junction of the horizontal tube branch 46 with a vertical branch 47 of the aerating tube. A. removable cap member 48 is pro` vided to giveaccess to the valve 44 and adjacent parts. Y

The valve 44 is provided with an actuating stem 49Wliich Vextends through the lube branch 46 and terminates in an actuating member 50 adapted to be directly engaged by the valve 36 of the dispensing faucet structure. A spring 51 normally holds the parts in condition to hold the s xat 44 in engagement with the scat 45.

The branch tube 46 communicates by means of a tubular member 52 willi an air inlet port 53' through which air enters the fill lill) lll] aeratingsystcmto find its way into `the interior `of the mass of liquid in the conmeansA are provided for treatingin any de`` siredinanner the air supplied tothe aeration device so that theliquid mayin turn be subjected to any desired treatment` W hat we claim is: f i i 3 A l..
